SPECIFICATION forming part of Letters Patent No. 247,936, dated October 4, 1881.

Application filed July 23, 1881. (No model.)

To all whom it may concern:

Be it known that we, JAMES A. MALONEY and FRANZ BiiRGER, ot' the city of Washington, in the District of Columbia, have invented a certain new and useful Regulator for Electrophores or Secondary Batteries; and we hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which Figure. 1 is a vertical sectional view; Fig. 2, side elevation, showing exterior of regulator; and Fig. 3 is a section through block D on line I 5 A represents a secondary battery, to which the regulator is to be attached. A represents the casingof regulator; B, an electroanagnet; C, rod formed of copper wire; D, block of carbon; E, bow-spring; F, set-screw; G G,

binding-posts; H, soft-iron baryh, space between soft-iron bar and helix; (1. a, wire-counections to electro-magnet; b, tension-spring; ff, binding-posts. g is a spring connecting wire rod C and helix B; (1, slot in block D. m

m are wires completing circuit through an electric light. 172 m are wires from generator of current to electrophore or secondary battery.

Our invention relates to a novel method and means for regulating the flow of the electric current to or from an electrophore or secondary battery.

Our invention consists in a regulator attached to one pole of an electrophore or see- 5 ondary battery, so that the flow of the electric current can be controlled in use either as a source of light or power. Its action being automatic,-it is both economical and effective.

To enable others skilled in the art to make and use our invention, we will proceed to describe the construction and operation of our invention.

A piece of soft iron is suspended by means of a spring and set-screw within a helix or spool. To the end of the soft-iron bar is attached a copper wire, a, working in a groove, d, in a block of carbon, and kept in position by a rubber spring, E, said block of carbon resting upon a metallic base. As the flow of the current from the electrophore or secondary battery increases the bar of softiron within the helix becomes excited and moves the copper rod upward from the metallic base, leaving the wire in contact with the block of carbon, which offers a greater resistance to the 5 5 current, and greater as the copper rod moves in a vertical line along the block of carbon,

so that with every increase of potential within the electrophore more resistance to the flow is offered through the action of the wire upon the block of carbon through the electromagnet.

When it is desired to use the electrophore or secondary battery with an electric light, and not interposed between the light and generator, the amount of light can be regulated by the set-screw F.

Such a device as shown in the drawings is of special value in the use of electrophores or secondary batteries, inasmuch as it enables the user to control the lights upon the circuit and control their intensity with the same certainty and expedition as gas can be controlled.

A small electrophore or secondary battery can be placed in circuit with one or more lights 7 arranged at a distance from one another upon the same circuit.

We do not confine ourselves to any precise form of coustructiu g the regulator, as any form of regulator for the current in an electrophore 8o or secondary battery may be used without de parting from the spirit of our invention.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

In combination with an electrophore, the electro-inagnet B, wire rod C, resistance-block D, spring E, set-screw F, spring I), and binding-posts ff, substantially as described,and for the purpose set forth.
